Coals

That's like carrying coals to Newcastle.

We can get many coals here.

The coals are burning red.

Whoops! There aren't many live coals left! Go make some kindling would you?

I once saw a man walk barefoot over hot coals.

My teacher found out that I was skipping class and he raked me over the coals.

His mouth was as wide as an oven, his teeth like yellow fangs, and his eyes, two glowing red coals.

His grey and lifeless eyes burned like two hot coals.

The eyes of the skull suddenly began to glimmer and to glow like red coals, and wherever the three turned or ran the eyes followed them, growing larger and brighter till they flamed like two furnaces, and hotter and hotter till the merchant's wife and her two wicked daughters took fire and were burned to ashes. Only Vasilissa the Beautiful was not touched.

I'm being raked over the coals.
